LINE-CONNECTING DEVICE.

Patented June 26,1906.

Application filed June 18,1904. serial No; 213,087.

To all whom may concern.-

Be it known that I,,JosEPH H. WARREN, a c1t1z e n of the United States, residing at Ohi- Q cago, in the county of-Cookand State of Illioverhead wire, such as a telephone or telegraph wire.

I will describe my invention particularly by reference to the accompanying drawings, andthe parts, improvements, and combinations which I regard as novel'will be pointed out in the appended claims.

. Figure 1 is a view in elevation of the re- 'movable sections comprising the line-connecting pole of my invention. Fig. 2 is a longitudinal sectional view of my device, showing the same connecting a telephone set with an overhead wire leadin to a distant station. Figs.

3 and 4 are detai sectional views illustrating the manner of cou ling the sections. Fig. 5

is a detail view 0 the clip for engaging an overhead wire. Fig. 6 is a view of a portion of two sections to illustrate the manner of connecting and locking them, and Figs. 7 and 8 are detail views of the cleat whichI employ.

The same characters ofreference are used to designate the same partsin each of thefigures of the drawings.

The line-connecting'device illustrated comprises a pole, preferably of bamboo, having removable sections a In adapted to be coup- 4 pled, as hereinafter explained, the section a being the upper or top one when assembled, b the intermediate, and c the lower'or base section. While" I have only illustrated Jone intermediatesection, it will be understood that as many more could be used as desired or simply two sections employed, according to the height of the wire to be connected with.

The section a carries at its u per end a clip 11, which may be a' cylinder (1, tting over the end of the section a, its upper end being curved and cut away to form a hook d. A tongue (1 is secured to said cylinder with its free end extending up adjacent to the inner" surface ofthe hook (2 said tongue being adapted to press a wire held by said hook into firm engagement therewith. The upper surface of the tongue d is preferably roughened, as shown, so that the tongue will clean awire with which it is brought into engagement and make better contact therewith. The sides'of the tongue at the u per part thereof are bent in to form a curve surface, so that kinking of the wire which it engages or other injury will be revented. The I ower end of the section a carries a metal ferrule e, which is adapted to fit intoa metal socket e,-carried by one end of the section b. L-shaped slots 1) b are provided in the ferrule e, and a transverse pin a, passin throu h the socket e, is adapted to enter sai slots when the ferrules are coupled. By twisting the ferrule 6 when the same is inserted the pin 6 enters the transverse portions of the slots 1), so that the two sections are securely lo cked together, the structure forming, in effect, a boyonetjoint. The clip (1 and ferrule c are electrically connected by a conductor 1, extending through the interior of the section. The opposite end of the section b is provided with a ferrule f, similar'to the ferrule e before described, and a conductor 2 electrically connects the socket e and ferrule f of section b, said conductor passing through theinterior of the section.

, The up er end of the base or bottom sec, tion 0 of th similar to the socket e above described, with the exception that it is rovided in addition with an inner tube or soc et 9, concentrically disposed with relation to the outer socket 9, so that the section 0 may be coupled with sections of different sizes. The ole considered as a unit is gradually tapere toward the tip. The ferrules and sockets of the different sections are therefore of difierent diameters.

, .The ferrule e ofsection a and socket e of section b are the smallest and are adapted to be coupled together. end of section I) would of course be of somewhat greater diameter than ferrule e, and the The ferrule f at the lower e pole is provided with a socket g,

socket g, withwhich the ferrule f is coupled, is

correspondingly larger than socket e; The provision of the inner concentric tube g in association with socket 9 (said tube beingof the same diameter as socket e of section b) makes it possible to couple the sections a c by.

simply inserting the ferrule e of section a within said tube g. A conductor 3 extends from the socket 9 through the interior of the section and emerges through an opening it therein. Said conductor may be connected with suitable electrical signal transmitting and receiving mechanism,'such as the telephonesetA. (IllustratedinFig. 2.) The coupling of the metal ferrules and sockets to unite the sections a b 0 serves to electrically connect the conductors 1, 2 and 3, which form, in effect, one continuous conductor extending from the clip to the telephone set.

When the pole is not in use, the conductor 3 may be wrapped upon cleats h h, which are carried by the base or bottom section 0. Each of the cleats it comprises an open ring h, whose ends are extended to form ar-ms h 71?. To secure one of said cleats to thepole, the two arms h h are forced apart to spread or open the ring, and the ring is then fitted upon the desired section of the pole. The arms are then brought together and fastened in any desired way, as by riveting. In case the diameter of the section is so great that the arms may not be brought together after the ring is placed on said section I preferably insert a metal piece k between said arms and fasten the three parts together. The cleat is thus in either case rigidly held in place upon the pole.

Where the ferrules are joined to the sections the bamboo is preferably reinforced by centrally-bored wooden plugs 'L i, and openings 7c 7c are provided in the base of each of the sockets e g, through which dirt or foreign matter, which might interfere with the completion of a good electrical connection between the metal ferrules, may escape.

In the operation of my device the sections are coupled together and the clip d brought into engagement with a telephone or telegraph wire, as desired, and a suitable signal receiving and transmitting mechanism connected with the conductor 3. Referring to Fig. 2, I have shown the clip d in engagement with a wire 4, extending to a distant station B, the clip being connected by way of conductors 1 2 3 with the telephone set A. Signals may thus be transmitted to the distant station and conversation carried on.

I claim 1. In a line-connecting device, in combination a hollow pole comprising a number of removable sections, conductors within said sections, a cli carried by the top. section adapted to make e ectrical connection with an overhead wire, said clip being connected with the conductor within the top section, and metal ferrules for uniting said sections and connecting said conductors.

A line-connecting device consisting of a pole, the diameter whereof increases from a minimum at the top to amaximum at the base, said pole comprising a number of separate lengths or sections removably fitted together by ferrules and sockets, each ferrule and-socket having a diameter different from the remaining ferrules and sockets, a clip carried by the upper section of the pole adapted to engage a wire, a conductor connected with said clip and a tube within one of the larger sockets, said tube'being of a diameter adapted to fit the ferrule of an upper section, said tube and socket being concentrically disposed; whereby said larger section may be coupled with sections of different sizes. 5. In a line-connecting device, the combination with a pole, of a clip carried by said pole adapted to make connection with a conducting-wire, a conductor connected with said clip, and cleats carried by said pole upon which a portion of said conductor may be wound, each cleat comprising an open ring h fitting upon said section, arms h 7L2 formed by the ends of said ring, and means for fastening said arms together to close said ring and securethe cleat rigidly in place upon the pole.

6. In a line-connecting device, the combination with a pole, of a clip carried by said pole adapted to make connection with a con ducting-wire, a conductor connected with said clip, and cleats carried by said pole upon which a ortion of said conducting-wire may be Woun each cleat comprising an open ring h fitting upon said section, arms k h formed by the ends of said ring, a metal piece It placed between said arms, and means for securing said arms and metal piece together, whereby the cleat is held rigidly in place upon the pole.
